Discover the new revolutionary JULIUS-K9® harness: the JK9®GO dog harness brings together all the advantages of the previous JULIUS-K9® harnesses in one model and is the result of more than 25 years of experience in designing and manufacturing harnesses in Europe. This versatile harness is suitable for all dogs and combines a no-pull Y-harness with a metal ring on the front with a control harness featuring a strong handle on the back for maximum safety on walks. Like all JULIUS-K9 harnesses, it can be personalised with your dog’s name or any text of your choice thanks to the hook-and-loop logo patch on the back. But this model goes even further: the logo conceals a discreet compartment for a GPS tracker, compatible with devices such as AirTag or KokoTag – combining style, safety and technology with ease.
This harness offers a two-point attachment system (front ring + back ring) to help control and hold puppies, dogs that pull or dogs that do not yet walk calmly on the lead. The ultra-strong handle on the back allows you to bring your dog close to you quickly when passing another animal or in stressful situations (crowds, roadside, etc.). It is extremely robust and tested for 10,000 repeated pulls at the maximum recommended body weight for each size. The leash attachment ring is made of stainless steel for long-lasting durability and is tested for loads greater than 10 times the dog’s indicated weight per size. All our stainless-steel components are made in Germany from high-quality metal. Our long-standing cooperation with German stainless-steel suppliers has enabled us to guarantee a consistent level of quality for more than 20 years.
The JK9®GO harness is equipped with the Duo-Flex® system, which adapts to the dog’s movement so that the dog hardly feels the harness when walking. This elastic system increases the flexibility of the harness and absorbs shocks when the lead is under tension. How it works: the shock absorber placed between the leash ring and the ring connecting the front straps reduces the jolts caused when the dog pulls on the lead. The ergonomic design of the JK9®GO harness is inspired by its “big brother”, the IDC®Longwalk, and provides optimal comfort even on long walks. The lower Y-strap is narrow and padded to minimise contact with the skin and prevent chafing, regardless of the activity. The wide belly strap distributes the pulling force evenly across the chest.
Easy to put on and take off thanks to buckles on each chest strap: there is no need to lift the dog’s paws through the harness – simply slip it over the head. The new wide, supple straps are easy to adjust so that the harness can be perfectly fitted to any dog’s body shape, regardless of breed. The harness has four adjustable straps, and this multi-level adjustment system allows it to adapt to many different breeds and to be used for all dog sizes. Thanks to its very large adjustment range (16 to 20 cm at the chest and 6 to 15 cm at the neck), it is also suitable for growing dogs or dogs whose weight frequently changes.
Lightweight and durable, the JK9®GO dog harness is one of the best harnesses for daily walks and sports activities. It is made from four layers of technical material: a water-repellent outer layer of PTP polyester that is easy to clean, a soft, flexible foam layer for long-lasting comfort, a tear-resistant reinforcement layer for extra strength and a breathable, skin-friendly lining certified according to OEKO-TEX®. All these technical materials are made in Europe and are known for their strength and durability. The seams and finishes are executed with great precision and high-quality workmanship to ensure a strong, hard-wearing product that will accompany your dog every day. The reflective edges of the JK9®GO harness ensure optimal visibility at night, increasing your dog’s safety on walks.
The strength of the JK9®GO harness is confirmed by pull tests carried out under the supervision of independent bodies and meets the SFS-EN ISO 9001 quality standard:
Non-toxic materials in accordance with OEKO-TEX® 100
High-quality, particularly durable plastic buckles and fasteners
Stainless-steel metal parts resistant to weather conditions
Straps made in Germany, originating from the automotive industry
To personalise your harness with a classic white-text logo, enter your chosen text in the field “Option: harness personalisation (72h lead time)”. Please only use letters and numbers of the European alphabet (any heart symbol, Chinese, Japanese, Arabic or other characters will automatically be removed from the text) and a maximum of 15 characters (the more characters, the smaller the letters will appear). The text will be reproduced exactly as entered, respecting upper and lower case. Each black strip features the phosphorescent wording “Licensed by JULIUS-K9®” and your text in non-reflective, non-phosphorescent white letters, with hook-and-loop backing on the reverse.

| Instructions | Easy to put on and take off thanks to the buckles on each chest strap: there is no need to lift the dog’s paws through the harness, you simply slip it over the head. The new wide, supple straps are easy to adjust so that the harness fits the dog’s body shape perfectly, whatever the breed. |
| Composition | The technical materials are carefully arranged in four layered components: a water-repellent outer shell encloses a comfortable foam layer, a neoprene reinforcement layer for extra strength, and a breathable lining certified according to OEKO-TEX®. All fabrics are manufactured in Europe and are renowned for their strength and durability. All raw materials are based on polyester, polypropylene, polyamide (nylon) and cotton sourced from Europe, mainly from Hungary and Germany. The metal and stainless-steel rings are made in Germany. The plastic buckles and fasteners are produced in Hungary in our Julius-K9 factories from high-quality, break-resistant plastic. This material has three advantages over conventional metal: it is lighter, it does not rust and its more rounded edges improve the durability of the fastening seams. Each buckle is secured with abrasion-resistant nylon stitching. |
